在现代工业和科学技术中,性能各异、品种繁多的金属材料起着十分重要的作用。具有特殊性能的金属材料的发现可以分成两类:一种是有目的、有计划的制定实验方案,经过细心地探索和研究而发现的材料;再一种似乎是“偶然”的发现,人们本来是为了发现某一种预想性能的材料,结果却意外地发现了另一种很有意义的性能,从而导致新材料的发现。一些伟大的发现之所以偶然,是由于在发生某些不平常的现象时,有一个观察力敏锐的人注意到,并着手去找出其原因。下面就是几个特殊性能金属材料偶然发现的例子。
In modern industry and science and technology, different performance, a wide variety of metallic materials plays a very important role. The discovery of metallic materials with special properties can be divided into two categories: one is a purposive and planned experimental program, a material discovered after careful exploration and research, and one that appears to be “accidental” Is to discover a certain kind of expected performance materials, the result unexpectedly found another meaningful performance, leading to the discovery of new materials. Some of the great discoveries were accidental because one of the most observant people noticed and started to find out the cause of some unusual phenomenon. Here are some examples of accidental discovery of special-purpose metallic materials.
